FAQ
What is the maximum operating frequency of the M30843FHFP#U3?
The M30843FHFP#U3 achieves its shortest instruction execution time of 31.3 ns at a BCLK frequency of 32 MHz, with VCC1 supplied at 4.2–5.5 V. At 24 MHz BCLK and VCC1=3.0–5.5 V, the minimum instruction cycle extends to 41.7 ns. The PLL frequency synthesizer enables flexible clock scaling while maintaining CAN and serial timing accuracy.
Does the M30843FHFP#U3 support CAN FD or only classical CAN?
The M30843FHFP#U3 supports only CAN 2.0B (Classical CAN) as specified in its documentation. It does not implement CAN FD features such as variable bit rate, extended data length, or CRC enhancements. For CAN FD requirements, consider alternatives like MB9BF516RPMC, which explicitly includes dual CAN FD controllers.
What package type and footprint does the M30843FHFP#U3 use?
The M30843FHFP#U3 uses the PRQP0100JB-A package: a 100-pin plastic LQFP with 14 mm × 14 mm body size and 0.5 mm lead pitch. This footprint is compatible with standard reflow soldering processes and matches industry-standard 100-pin LQFP land patterns used in automotive and industrial PCB designs.
How many A/D input channels does the M30843FHFP#U3 provide?
The M30843FHFP#U3 provides 26 analog input channels for its 10-bit A/D converter, as confirmed for the 100-pin package variant. These include dedicated pins (AN00–AN07, AN20–AN27, KI0–KI3, ANEX0/ANEX1) and multiplexed port pins - sufficient for multi-sensor monitoring in motor control and environmental sensing applications.
Is the M30843FHFP#U3 pin-compatible with other M32C/84 family members?
The M30843FHFP#U3 shares the 100-pin LQFP (PRQP0100JB-A) package and core peripheral set with other M32C/84 variants like M30842FHP#U3 and M30841FHP#U3, but pin assignments differ for memory interface and certain I/O functions. Direct pin-for-pin replacement requires verification against individual device pinout tables - especially for CS, WR, RD, and A/D channel mappings.
